Perhaps you should try some spelling variations:
"berkeley index apertures" » "berkeley coded apertures", "berkeley new apertures", "berkeley finite apertures", "berkeley andrew apertures", "berkeley unix apertures", "berkeley one apertures"
"berkeley annex lectures" » "berkeley ann lectures", "berkeley andrew lectures", "berkeley unix lectures", "berkeley tanner lectures", "berkeley annual lectures", "berkeley index lecturers"
"berkeley index lectures" » "berkeley andrew lectures", "berkeley unix lectures", "berkeley one lectures", "berkeley index lecturers", "berkeley indexes lecturers", "berkeley mendel lectures"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("berkeley annex lectures") OR ((("berkeley index lectures") OR ("berkeley index apertures")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"berkeley annex lectures\") or (((\"berkeley index lectures\") OR (\"berkeley index apertures\"))))".
• Removing quotes may allow a broader search: (( berkeley annex lectures ) or ((( berkeley index lectures ) OR ( berkeley index apertures )))).
• Adding a wildcard symbol may retrieve word variants: (("berkeley annex lectures") or ((("berkeley index lectures") OR ("berkeley index apertures"))))*.
